Visitor pattern is suitable for systems with relatively stable data structures. It disconnects the coupling between data structures and operations acting on structures, allowing the set of operations to evolve relatively freely.

一，本人无法将出现在脑海中的可怕念头像正常人一样驱散并且正常生活；二，不可能将出现在他们脑海中的可怕想法付诸行动。这类强迫症称谓纯粹强迫思想，早起研究认为纯粹强迫思想的人不会有强迫行为或者仪式行为，但事实上并非如此，许多人会有轻度的心理仪式行为来中和这些可怕的强迫思想引起的焦虑或者痛苦。（Steketee, 1993；Freeston和Ladouceur, 1997）

Overlay mode. Whether the pixels are Multiply or Screen blended depends on the underlying color. The colors will be mixed, but the brightness details of the highlights and shadows of the underlying colors will be preserved.
In addition to solving the port problem of A, the serial number problem also needs to be paid attention to. The serial number corresponds to the sliding window. The fake TCP packet needs to be filled with the serial number. If the value of the serial number is not in the sliding window of B when it is sent to B before A, B will actively discard it. So we need to find the serial number that can fall into the sliding window between AB at that time. This can be solved violently, because the length of a sequence is 32 bits, and the value range is 0-4294967296. If the window size is like 65535 under Windows I caught in the above figure, I only need to divide, and I know that at most I only need to send 65537 (4294967296/65535=65537) packets to have a sequence number fall into the sliding window. The desired value can be calculated quickly by exhaustion on multiple control hosts.
